Translation of line from c# to php

[fbio]

  byte[] hashedData = hmacGenerator.ComputeHash(tarrrr);
        byte[] codeArray = new byte[5];
        try
        {
            byte b = (byte)(hashedData[19] & 0xF);
            int Point = (hashedData[b] & 0x7F) << 24 | (hashedData[b + 1] & 0xFF) << 16 | (hashedData[b + 2] & 0xFF) << 8 | (hashedData[b + 3] & 0xFF);

            for (int i = 0; i < 5; ++i)
            {
                codeArray[i] = CodeTranslations[Point % CodeTranslations.Length];
                Point /= CodeTranslations.Length;
            }
        }

I'm really interested in how this line looks at the PHP.

Based on the assumption that yours is hmacGenerator It's a SHA1 hesh (in 20-bite length) and it's like:

  $hashedData=sha1($tarrrr,true);
  $b=ord($hashedData[19]) & 0xF;
  $Point=unpack("N",substr($hashedData,$b,4))[1] & 0x7FFFFFFF;
$arrLen=count($CodeTranslations);

$codeArray="";

for ($i = 0; $i < 5; $i++):

$codeArray .= chr($CodeTranslations[$Point % $arrLen]);

$Point = (int)($Point/$arrLen);

endfor;
